Torque Sensor and Load Cell Calibration
Calibration is the comparison of a load cell or torque sensor to a reference standard with a known accuracy. The goal of calibration is to determine the accuracy of the instrument, establish traceability, and establish a direct relationship between a known applied load, the reference standard, and the output of the sensor.
Like all measurement instruments, load cells and torque sensors are subject to aging. Mechanical stress and fatigue experienced through normal use will cause sensors to “drift” over time. Although this instability cannot be prevented, it can be identified and corrected by a well-designed calibration program.
